When should a technician NOT be grounded?

A technician should not be grounded when making live adjustments because grounding in this context could create a path for electrical current to flow through the technician's body. This could lead to serious injuries or even fatalities, as the technician would be exposed to the electrical live circuit.

In contrast, grounding is encouraged in other scenario such as when working on unplugged equipment, as it helps to prevent static discharge that could potentially damage sensitive components. Similarly, during static electricity tests and while discharging a grounded CRT, grounding can ensure that the technician and the equipment being handled remain safe from harmful static discharge.

Understanding when to be grounded or ungrounded is crucial for a technician's safety, particularly in situations involving live electricity where grounding can be the difference between safety and danger.
